Pre-decisional – for planning and discussion purposes only Six Technology Challenges

1. Interplanetary Getting to environment Interplanetary CubeSats Taxonomy

• Launch off C3>0 ~ballistic traj – Cruiser • Depart from “Mothership”, 10s to 100s m/sec 2. Telecommunications – Companion – Orbiter – Lander – Impactor 6. Maximizing downlink info content • Self-propelled 3. Propulsion 1 – 10 km/sec/yr (where needed) 5.Instruments – Electric – Solar Sail

4. Navigation 5 5 Pre-decisional – for planning and discussion purposes only NIAC Results (our forecast)… “Investigation during our Phase 1 work has demonstrated the feasibility of a new class of missions that can open Solar System exploration to a broader community of participants at lower cost. Looking ahead to the 2020s, the work proposed here will enable missions that depart Earth’s vicinity several times a year—at one-tenth the cost of current Discovery missions—to a variety of destinations with focused goals of small body science, lunar and planetary investigations, space physics, heliophysics, and technology development. Interplanetary CubeSat missions will be mounted by NASA Centers, well-equipped universities, and small businesses in ways that were simply unattainable when mission costs were measured in multiples of $100M.”

• New architecture ! new mission class ! broader community involvement • Missions leave Earth a few times a year • Focused objectives (<

Lens/immersion medium Overview The spectrometer is a miniaturized version of the compact Dyson design form that is currently under development at JPL and elsewhere. Our work will extend our concept from the PRISM airborne spectrometer, tested in early 2012, and a fast, wide-field imaging spectrometer demonstrated as a laboratory breadboard through NASA’s PIDDP program. Detector Instrument Electronics • Detector similar to the one flown on PRISM (Portable Remote Imaging Spectrometer) • Data processing based on a heritage design • Consumes ~1W of average power • Detector interface and data storage would be a new design feature Pantazis Mouroulis 2011 11 Pre-decisional – for planning and discussion purposes only Among the instruments that have come to or are approaching fruition at CubeSat size… • Imaging spectrometer (shown; Blaney, Mouroulis, et al.) • Magnetometer • Microwave radiometer • Radar • pick your favorite…
